An intermittent fault is a fault that does not occur all the time, it could happen that the customer reports a fault and you do not find this same fault while testing. It is best to rule out operator error first by ensuring the customer does the same test that you would do to ensure there is really a fault. All faults described below are what is reported by the customer but not found by you on first inspection.

If a wire is loose and connects sometimes and not other times you would need to do the bump test. Usually by bumping the unit the loose wire will stop working and you can find the fault. This is done by bumping the unit on a piece of rubber or wood. If the unit resets (via the power being switched on and off) you will see the light flash. If its a suspect Touch port wire you would need to retest after a few bumps. Results may vary

This is done to show the unit clocking many points. The best way to do this is to give the unit to a guard in your area to use when they patrol. It might take some time to find the fault this way but it does simulate the proper use.

• First check that other batons download on the clients PC it might be their computer or download station
• It might be a loose wire which connects fine by you but not at the customer, do bump test as above

• A common report is that the unit is not clocking properly when the guard uses the unit but works fine when the customer uses it. this usually indicated that the guard is sleeping and not clocking.
• It could be a loose wire do the bump test and possible the multiclock test
• If you still cannot find fault tell the customer to place a point by their computer and clock it before and after downloads if the point is at the beginning and end of all their reports they know the unit is working properly.
